[Abstract]
Longxuan 1 is newly bred winter wheat line from the variation per plant of outside test lines Zhongliang 9589 through a multi generational pedigree method. In 2012 — 2014, the average yield is 4 745.85 kg/hm2 and 10.9% higher than that of the check variety Longzhong 1 in winter wheat dryland area test of Gansu Central. The result shows that the variety is semi winter, growth period is 286 d, plant height is 106 cm, ear length is 7 ~ 8 cm, grains per spike is 52, 1 000 grain weight is 43.6 g, bulk density is 788 g/L. It is resistance to cold, drought, high yield, stable yield. The result indicates that the seed crude protein (dry basis), wet gluten (14% moisture basis), lysine(dry basis), sedimentation value of (14% moisture basis) are 116 g/kg, 239 g/kg, 4.35 g/kg, 37 mL, respectively. In addition, the seedlings of mixed bacteria are immune at the seeding stage, the lines is moderate resistance to CY. 32, CY 33, Zhong 4-1, G22-14 and mixed bacteria at the adult stage. It is suitable to be grown in arid and semi arid of central Gansu, and similar ecological conditions.
